CDIP Products

Once data have been acquired and processed, CDIP makes them
available to users in a variety of forms. In addition
to CDIP's standard data files, the web site offers a wide range
of tools and services that provide graphical, tabular, and
text analyses of both realtime and historic data. In this
way all users - from researchers looking for the most detailed,
extensive data set possible, to surfers just checking the
waves - can find the information that they need.

When browsing CDIP data, there a couple of points to keep
in mind. First, the times given on files and data values
are start times, from the very beginning of the sample
period. Second, summary values - wave height,
average period, sea surface temperature, etc. - are
computed for sampling periods that are generally near
30 minutes or one hour in duration.

description of its format.

CDIP has a highly-developed data collection, processing, and
analysis infrastructure which facilitates the integration of
its ocean measurements into
SCCOOS and
CeNCOOS.
Since its inception in 1976, CDIP's goals have reflected many of
the same emphases as recent ocean observing initiatives, namely:

CDIP's website is also equipped to present a range of text and graphic
products based on spectral data submitted by cooperating agencies. For
details on this process, please contact us and refer to our
data submission
guidelines.

The USACE's Wave
Information Studies (WIS) program makes extensive use of CDIP buoy
observations for model validation. The relative locations of WIS output points
and CDIP buoys (as of Jan 2016) can be viewed in a kml file.

CDIP is an active member of the QARTOD (Quality Assurance of Real-Time
Ocean Data) effort. This is an IOOS community effort to standardize
quality assurance and quality control parameters among data providers.
Thus far, waves, in-situ currents, remote currents and CTD have been
addressed. Summary tables of quality control measures have been
developed for both waves and in-situ currents; refer to the links
below.

To assist with the wave measurement community's comparison and
validation of various wave sensors, CDIP has developed a
a special tool for analyzing spectral wave data. Details from co-location
experiments and the tool itself can be accessed online. In partnership with
the Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM)
, wave sensor intercomparison test results may also be found on
JCOMM's Wave measurement Evaluation and Test page.

All of CDIP's data sets are described by detailed metadata, which is
continuously updated and available online in a number of formats.
FGDC-compliant metadata are included, in both HTML and XML formats.
The metadata for any specific data set are accessible from the
station pages in the historic section of the website.
In addition to the standard, on-the-fly web pages, static XML
metadata files are available for download or harvesting from a
web-accessible folder.

To aid both research and education efforts, CDIP produces a number of
customized products for different institutions. Some of these products
are specialized plots and data files, geared towards a specific
investigation; others are general display pages, intended to educate the
public and promote awareness about the numerous oceanographic
resources available on the web today. Listed below are examples of
the various types of custom products that have been generated.

•
Products that are automatically tranferred to associated agencies
in near real-time

Every thirty minutes the latest measurements
from CDIP's buoys are transmitted to the
NDBC and the NWS. Please see the next section of the documentation,
Access Instructions,
for more details on these collaborations.

•
Products that are prepared for associated agencies and
available via the web

Diablo Canyon wave height and period forecasts are updated
hourly for use by managers at Pacific Gas and Electric's
Diablo Canyon Nuclear Power Plant. (Latest forecast
)

Detailed wave modeling is performed in the San Pedro Channel/Long
Beach Harbor vicinity to faciltate the operation of the numerous
shipping operations in the area. (Latest model
)

•
Products and web pages that are customized for specific venues

In SIO's Birch Aquarium
a number of pages summarizing CDIP activities - as seen
in the thumbnails below - were set up in a special display to
help educate and inform visitors to the aquarium.

Informational web slide shows have been designed to allow the
display of CDIP products at public events such as the
San Diego County fair. These shows include the standard
slide show and the
split-screen slide show.

In the early days, the most efficient and cost-effective way for
CDIP to disseminate its data was via monthly and yearly reports,
printed and distributed to interested agencies and researchers.
But by the mid-1990s, however, things had changed dramatically,
and the program began to focus its efforts on distributing data
via the internet. Today, all of CDIP's data are available on the
web, on a highly-trafficked site - http://cdip.ucsd.edu/ -
that is continually updated with the very latest data.

Automated access to data on the CDIP site can be easily arranged
through the use of our cgi scripts. For more details, please
refer to the
Data Access FAQ.

The latest data from CDIP stations are also available through
the
National Data Buoy Center's web page and
Dial-A-Buoy
service. Every thirty minutes the latest measurements
from CDIP's buoys are transmitted to the NDBC in FM-13 format.
The NDBC then distributes these data through through their
Advanced Weather Interactive Processing System (AWIPS).
In the list at left are Station IDs for all buoys currently
accessible through the NDBC.

CDIP data and products are freely available for public use, provided that
they are not altered in any way. When
